It was the first plant genome to be sequenced, completed in 2000 by the Arabidopsis Genome Initiative.[1] The most up-to-date version of the Arabidopsis thaliana genome is maintained by The Arabidopsis Information Resource (TAIR).[2]

Much work has been done to find out what its 27,000 genes and 35,000 proteins do.[3] Arabidopsis is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing.
